Title: Improvements in or relating to thermionic valves and thermionic valve circuit arrangements for use on short waves
IPC: H01J25/52
Filed: 1936-11-28
Abstract: 489,608. Electron oscillators and circuits therefor. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Nov. 28, 1936, No. 13963/38. Convention date, Nov. 30, 1935. Divided out of 488,094. [Classes 39 (i) and 40 (v)] An electron-discharge device has a source of electrons K and at least two further electrodes A1, A<1>1 arranged at increasing distances from the source, the inner electrode A1 being electron permeable. A magnetic field perpendicular to the plane of the paper causes the electrons to follow cycloidal paths. A tuned circuit L, C, the time of oscillation of which corresponds approximately to the time of revolution of the electrons, is connected between the electrodes A1, A<1>1. An electron approaching A1 in correct phase gives up its energy to it and describes a cycloidal path of diminishing radius (full line), finally arriving on electrode N with low velocity. An electron in wrong phase, however, performs a path of increasing radius (dotted line) and soon passes through the permeable portion of A1 to enter a space containing an electrostatic field of opposite phase to which it can give up its energy. Electrons emitted at any time thus contribute usefully to oscillation generation. In the form shown, further electrodes A2, A<1>2 are disposed symmetrically on the opposite side of the cathode K which is provided with a space charge electrode Gz, concentrating electrode Z and control plates Gs. In modifications, plane electrodes are disposed on one or both sides of an extended cathode ; or two cylindrical electrodes surround a cathode, the electrode separations being equal. The perforated electrodes may be made secondary-electron emissive so that any wrongly phased electrons arriving on these electrodes will cause an excess of secondary electrons to be emitted and will consequently assist oscillation generation. The device may be provided with additional control electrodes for modulation, demodulation or stabilization. Specification 488,094 is referred to. The Specification as open to inspection under Sect. 91 includes Fig. 6 of Specification 488,094 and describes a retarding field valve comprising four cylindrical electron-permeable electrodes surrounding a cathode and connected by tuned circuits. The working of a split-anode magnetron is discussed theoretically. This subjectmatter does not appear in the Specification as accepted.

Filed: 1929-05-09
Abstract: 336,602. Lloyd, L. N., and Phillips Engineering Co., Ltd. May 9, 1929 Louvre and like floors; drying at particular temperatures and pressures; charging; discharging; heating-fittings. - Solid or semi-solid material is dried by passage from one to another of a series of trays heated internally or by a source located in close proximity thereto. The trays, which may be located within a chamber, evacuated or maintained at any desired pressure are superposed, the material being dumped automatically from tray to tray. The temperature of each tray is controlled independently. The trays 5, Fig. 1, each comprise tubular members 21, shown enlarged at 21a, 21b, Fig. 3, and movable members or bridge plates 22 which normally are adapted to close the space between the adjacent tubular members. Heating fluid, such as air or steam passes from a feed pipe along a branch pipe 27 to a header 24 where it is distributed through a diaphragm 23 to cross tubes 21b and into the annular space between the members 21<a>, 21<b> to return by way of a branch pipe 28. The trays may be heated electrically. The bridge plates of each tray have sprockets 30, Fig. 1, engaging a tilt rack 31 actuated by a pinion 32 such that the movement of the rack causes all the bridge plates of the tray to turn about their pivots and dump the material on to the one below, causing it to be turned over in the process. A belt or chain 41 is provided with a striker 42 or similar arrangement for actuating pinions 32 in rotation from the bottom upwards. Instead of a tilt rack the arrangement illustrated in Fig. 4 may be employed where an endless chain 33, Fig. 4, may be employed, suitably mounted in the chamber and actuating another chain 39 to rotate the sprockets 40 at the ends of the tubes, and thus operate the bridge plates. The bridge plates may be fixed rigidly to a carriage free to reciprocate above the flat upper surfaces of the tubes. In the arrangement shown in Fig. 1, the material is charged from an air lock chamber 1 first into a reciprocating feed tray 4 from which it drops on to the uppermost heating tray. This reciprocating tray runs on tracks 10 and mechanism is provided to operate such that when on the forward stroke the tray has reached a stop 17 the contents drop on to the top heating tray, and during this stroke the feed mechanism of a hopper 19 is rendered inoperative. On the return stroke the feed hopper mechanism is operated and a rotary paddle 20 is also rotated to spread the material evenly on the tray. A conveyer 6 takes the material from the lowermost tray and dumps it into a discharge air lock chamber 8. A preferred arrangement for distributing the material on to the uppermost tray is illustrated in Fig. 2, where an endless conveyer belt 56 is used comprising pivoted feed trays 59, which, as they pass over gaps 61 in that part of angle iron supports 57 for the conveyer, immediately above the heating trays, fall about their pivoted axes and discharge their contents on to the top heating tray.

Abstract: 1311266 Photo-electric pulse generator for sewing machine CLEVEPAK CORP 12 May 1971 [13 May 1970 11 Dec 1970] 14486/71 Heading G1A [Also in Division D1] In order to produce an electrical pulse train having a frequency which varies as the frequency of rotation of a shaft of a machine e.g. a sewing machine, a photo-electric pulse generator is coupled to said shaft. As shown, the generator comprises a body 27 containing a shaft member 23 journalled in bearings 29, 31. An enlarged portion 37 of the shaft has much of its cross-section cut away to form a 90 degrees sector cross-section 39. The body 27 has a transverse bore 45 eccentrically located in relation to the axis of shaft 23. In counter bores of bore 45 are carried a light source 47, e.g. a long life incandescent bulb or a gallium arsenide light-emitting diode and a photo-detector 49, e.g. a photo-transistor, having a fast switching time. The end of shaft 23 is coupled to shaft 21 of sewing machine hand wheel 13 by a rubber tube 17 stiffened by member 25. In operation, the 90‹ degrees sector alternately blocks and unblocks the light to the detector, and at the normal speeds of the machine e.g. 10-20 thousand RPM provides a mark/space ratio of substantially one. The pulse train representing one pulse for each stitch is used for synchronization of peripheral equipment e.g. a thread cutter operating after a predetermined number of stitches have been made. The waveform produced is especially suitable for control of semiconductor digital switching circuitry.

Abstract: 1,108,599. Pulse modulation circuits; unijunction transistor oscillators. GRUNDIG E.M.V. ELEKTRO-MECHANISCHE VERSUCHSANSTALT INH. MAX GRUNDIG. 31 March, 1967 [31 March, 1966], No. 14870/67. Headings H3T and H4L. In a circuit for converting a voltage change into a corresponding change in frequency of an output signal, the incoming signal U E  is supplied to a differential amplifier DV whose output is supplied to the base of a transistor T2 so that a capacitor C is charged via T2 and resistor RE and discharged via a unijunction transistor T1. The voltage across resistor R E  provides the other input to amplifier DV. By this means the voltage across RE is maintained equal to the input voltage causing the charging current and therefore the output frequency to be proportional to the input voltage. Alternatively to obtain greater input sensitivity the voltage may be fed back from a tap on resistor RE. The discharge time EB of the capacitor, Fig. 1, introduces an error which is greater the higher the frequency and to minimize this error it is arranged that charging is terminated at point U p 2 instead of U p 1 so that the total period extends from A to E instead of from A to B and the discharge time is effectively eliminated. This is achieved by connecting the base B2 of the unijunction transistor to an adjustable tap on the emitter resistor R R  of a transistor T3 whose base is connected to the base of transistor T2, the value of the base-to-base voltage of transistor T1 being set by adjustment of R R  so that the peak-point voltage drops to the value V p 2. A thermistor R H  in the base B1 circuit of the unijunction transistor compensates for temperature variations.
